more draft animals which arehitched abreast,

one of the animals traveling in the furrow and the'o'thers on the land and each animal requiring, say thirty inches space. Therefore, the line of draft of the team is at one side of the line of draft of the plows, which creates a tendency in the plows to run out of the land. This tendency is increased by the pressure on' the landside of the plow and the outer end of the plow moldboards, and to prevent the plow running out of the land, the

out furrow wheel is set so as to lead the plow into the land. As this lead would cause the rim of this wheel to dig into the landside, it is set at an angle, the plane of the wheel intersecting a vertical plane passing through the axis of the wheel. This angular inclination somewhat impairs the control of the plow by the front furrow wheel, causes a strain or thrust tangent to the s .okcs, and also causes the edge of the rim to i' ig into the bottom of the furrow.

The land wheel is usually placed back of the front furrow wheel and on the opposite side of the frame and assists to carry the weight of the frame which is usually vertically adjustable with the plows and with reference to the wheels. The rear furrow wheel or caster wheel serves to guide the plow and assists in turning. With the three wheels thus placed and the line of draft of the team nonco'incident with the line of draft of the lows, the draft traces are at an angle to the inc of forward movement and the draft is considerably increased. With the described arrangement the land wheel has little, if any, eil'ect in guiding the plow, this duty being imposed almost wholly upon thefront furrow wheel. There is also a tendency to throw too much of the weight on the frame on the furrow wheel a s the land wheel has usually been so placed that it forms a fulcrum over caster wheel in turning the plow.

which the frame tilts and the resistance to the plows tends to tilt the frame, thus throwing its weight on the front furrow wheel and the drait traces. I place the land wheel well forward, preferably at' a point about op )osite the front furrow wheel. This land wheel is alsoplaced at an angle to a vertical plane passing through its axis'and is also given a lead so as to counteract the tendency of. the plow to run outof the land; This wheel. so placed takes its proper share'of the weight of the frame and correspondingly relieves the furrow wheel,

and the forward tiltin of the frame is over come. The land wheel in this position serves the further purpose of relieving the thrust on the front furrow wheel spokes and assists to guide the plow. I To facilitate the latter func tion, said wheel is mounted so as to swivel or turn around its axis and therefore serves as a To give plenty of room for four or more draft animals, 1 place the pole connection on the landsidc of the draft connection instead of upon or near the front furrow wheel standard; and inorder to place the front furrow wheel and the land wheel under control of the team, I connect said wheelsto a art moving with the pole connection. connection between the wheels I preferably make adjustable and insuch manner that the land wheel may turn or swivel independently thereof in some positions, thereby permitting its caster effect. This connection is preferably made by employing rods, one for each wheel, the outer ends of the rods being pivotally connected to short arms projecting from the boxes or bearings of the respective wheels and their inner ends having threaded connection with an arm projecting from and turning with a standard which carries the pole casting. This arm is n'iadelonger than the arms carried by the wheel boxes or standards so that the turning movement of the, plow is itCC-(lBffLlKMh The rear or caster wheel proper 'is also preferably connected by a steering rod with the pole piece in the usual manner so as to prevent side thrust on the pole while ermitting the proper swing of the caster w ieel in turning the plowi In the drawings--l igure 1 is an elevation To overcome these defects,

upon the caster wheel 11, the furrow wheel 12, and the land wheel 13. The caster and furrow wheels are placed in the usual positions, but the land wheel 13 is located Well forward'and nearly opposite the front furrow wheel. This wheel is mounted on a short axle 14, formedon thelo'wer end of the standard 15, carriedin the sleeve 16, the latter.

forming a part of the casting bolted to the front corner of'the frame. On the lower end of the standard is mounted a three armed lever 17, one of the arms 18 being adapted to contactthe horizontal portion of the standard, the arm 19 being connected to the box 5 or hearing by the spring 20, and the arm 21 afiording a pivotal connection'for a rod 22 which extends inwardly to and has a threaded connection with an arm 23 on the lower end of the standard 24, which is mounted on v the frame and carries the pole castin 25. A

rod 26 has its inner end connecte adjustably with the outer end of the arm 23 and to an arm 27, carried by the sleeve bearing 28 of the furrow wheel standard 29.

30 represents a steering rod which is extendedrearwardl and connected by an arm 31 with the standard 32 of the caster wheel, the front end of the rod 30 having a slotted connection with an arm 33 carried bythe pole standard. It will be observed that the arm 23 is longer than the arms '21 and 27. It will also be observed that the pole casting 25 is placed on the land side of the draft connection which is represented by the clevis 34.

- It will be observed particularly by refer ence to Fig. 3 that the front furrow wheel is set at an angle and is also given a lead toward the land, and that the land wheel is also set at an angle and has a lead in the same direction. By means of the connecting rods 22 and 26, these wheels are placed under the-- control of the team through the pole connection, which serves tohold the wheels'in their set position, the tendency of the plows to run out oftheland bein counteracted by the set of these wheels. n turning either to the rightor left, as indicated in Figs. 7 and 8, the furrow wheel 12 will be turned by the pole, and by reason of the fact that the arm 23 is longer than the arms 21 and 27, the turning movement of the furrow wheel is accelerated and the stop 18 is withdrawn from contact with axle 14, allowing the land wheel to caster freely. The arm 17 has an axial movement on the standard ofthe land wheel so that in the turnin movement of the plow it is free to turn independently of its connection to the ole in.either direction, as in.- dicated in Figs. 7 and 8, while it becomes locked with thefpole connection through the arm 18 in the forward movement to prevent outward turning of said wheel. The spring 20 affords an elastic link to hold the arm 18 against the axle 14 in the forward movement 0 the plow and while passing over rough or uneven ground, and to assist in backing the plow, asshown in Fig.4. The connection of the steering rod 30 with its arm 33 permits the rapid acceleration of the turning movement through the caster wheel, and the rod 30 transmits the thrust of the caster wheel to the pole standard in such manner asto relieve the pole itselfof the thrust. It will be observed that the location of the pole'connec tion onthe landside of the draft connection affords plenty of room for the team, but

otherwise the location of the pole connection does not modify materially the function of 'the land wheel in the described posiilgipn'in controlling and guiding the plows, and therefore it is obvious that these features of myinvention are not necessarily interdependent.

' I have described my invention in connection with a gan plow and it is obvious that the location of t e pole on the land side of the draft connection is more important in such a plow because of the number of draft animals necessary in the operation of the gang plow.

The steering connections are also more important in a glow of this character because of the increase tendency to side draft where a gang is used, but some of the features of the invention are useful in the construction of a modern sulky plow, particularly with a plow makin a wide cut.

Whi e I have described with some articu- Y larity the features of construction, it is obvious that the same might be modified without departing from the spirit and sco e of the invention, and I do not, therefore, unit my invention to more structural details.
